Export sum of snmptrap for Prometheus.

It seems that Prometheus and Grafana have been defact standard at network monitering,
while 'snmptrap' is still used for traditional commercial network service infrastructure.

This snmptrap-exporter visualizes how many times and when snmptraps occured in order to trace network unstabilities easily.

InfluxDB or MongoDB stores snmptraps

{network deices} -> snmptrap -> {snmptrapd} -> syslog -> {fluentd} -> db-plugin -> {influxdb/mongodb}

Promethus scrape with snmptrap-exporter that counts traps occured within a fixed period.
